Answer: The statements are missing hence I will give you a summary of what the big bang theory .
answer : The big bang theory explains how the energies of every speck of the universe came together at a point ( very dense point ) and eventually exploded creating the various galaxies we have today
Explanation:
The Big bang theory describes how the Universe and the various galaxies that exist began some billion of years ago, It describes how the energies of every speck of the universe came together at a point ( very dense point ) and eventually exploded creating the various galaxies we have today
An object with a velocity (v) of 9 m/s and a linear momentum (p) of 72 kg.m/s, has a mass (m) of 8 kg.
<h3>What is momentum?</h3>
In Newtonian mechanics, linear momentum, or simply momentum, is the product of the mass and velocity of an object.
It is a vector quantity, possessing a magnitude and a direction.
The mathematical expression for momentum is:
p = m . v
where,
- p is the linear momentum of the object.
- m is the mass of the object.
- v is the velocity of the object.
An object has a velocity (v) of 9 m/s and its linear momentum (p) is 72 kg.m/s. We will use the definition of linear momentum to calculate the mass of the object.
p = m . v
m = p / v
m = (72 kg.m/s) / (9 m/s) = 8 kg
An object with a velocity (v) of 9 m/s and a linear momentum (p) of 72 kg.m/s, has a mass (m) of 8 kg.

Answer:
0.000439077936334 m
Explanation:
q = Charge of electron = 
E = Electric field = 
= Permittivity of free space = 
d = Distance between plates = 2 cm (assumed)
m = Mass of electron = 
The beam consists of electrons which means it has negative charge this means the upper plates will be positive and the lower plate will be negative.
The direction is upper to lower lower plate.
= Permittivity of free space =
Electric flux is given by
The charge per unit area on the plates is
Deflection is given by
The deflection is 0.000439077936334 m
Answer:
In a series circuit, the same amount of current flows through all the components placed in it. On the other hand, in parallel circuits, the components are placed in parallel with each other due to which the circuit splits the current flow.
Answer:
Part a)
Speed of the roller coaster is
Part b)
Since it is moving with non zero speed at some height above the ground
So we will have
Kinetic energy + Potential energy Both
Explanation:
As we know that there is no friction on the path
So here we can use mechanical energy conservation law
so we will have
Part a)
Part b)
Since it is moving with non zero speed at some height above the ground
So we will have
Kinetic energy + Potential energy Both
